A deposition has surfaced in the Kim Kardashian/Kris Humphries divorce in which the producer of Kim's reality show confesses Kim re-shot her reaction to Kris' marriage proposal ... problem for Kris -- it kills his fraud case.

According to the depo transcript -- obtained by Life & Style -- when Kris proposed to Kim on "Keeping Up with the Kardashians," a producer says Kim was "completely surprised" and didn't give a good reaction, so she asked that it be re-shot.

2 big problems for Kris:

1. Kris is alleging Kim fraudulently induced him to marry her. Since he proposed and she was surprised, it means it positively wasn't a grand scheme to dupe him.

2. Kris clearly knew she re-shot her reaction, so no matter what, he was in on everything.
